NGC 1385 by William Ostling, on Flickr

Full write up here: https://theastroenthusiast.com/ngc-1385-from-hubble/

NGC 1385 is a strange spiral galaxy in the constellation Fornax. Originally a normal spiral, interaction with other galaxies nearby distorted its shape. The center of the galaxy was pulled and rotated 90 degrees to the shape it appears in now.

So I finally made the moon shot I said I would do. It's been awhile I could do the shot since it has been too much clouds and I needed to wait to the right moon phase and time to do this, but here it is!
A moon with a true Earthshine and Moonglow with its true Starfield. Meaning these shots are from the same camera, lens at the same time (120 images used from the Timelapse shot between 18:07 and 18:09 2021-01-06)

Nice!

I'm usually unimpressed with Moon pictures. I usually find them either boringly black and white, or else the Moon is shown in exaggerated, unrealistic color. Well, your picture is quite different. There is color, and the color looks really nice, but it is not exaggerated. It looks "real". And the composition is attractive, too. There are really great details in the Sun-illuminated part of the Moon! And your picture gives us a great idea of what the Earthshine-illuminated Moon really looks like. It is quite dark, but I can make out the "Lady in the Moon".

Welcome to Starship Asterisk*!

2021 Sun Analemma in Taipei in the Morning and Afternoon
If you record the sun at the same place and time every day, you will find that the po-sition of the sun keeps changing. One year later, put all the suns in the same photo or make an animation in sequence, and you will see it draw a big figure of 8 in the sky exactly as the laws of physics tell us. This is really very exciting and moving! The tra-jectory of the sun in a year is called the sun analemma. The link to the video of the sun analemma in Taipei is as follows:https://www.youtube.com/watch?v=59MW1aqO7L4
Click to view full size image
The sun analemma seen on the earth is basically like a figure of eight, and the two circles of the figure-8 are of different sizes. This is related to the eccentricity of the earth's orbit and the tilt of the earth's rotation axis. The degree of the figure-8 tilt in the sky is related to the latitude of the observer's location and the recorded time.
In 2021, I spent a whole year in Taipei recording the position of the sun at 7:30 am and 4:30 pm. In the northern hemisphere, the summer solstice of the sun analemma in the morning is at upper left, and the winter solstice at lower right. As for the sun analemma in the afternoon, the tilt direction is different from that in the morning. The summer solstice is at upper right, and the winter solstice at lower left. Whether it is in the morning or in the afternoon, sun analemma has a small circle above and a large circle below. It is also worth noting that the intersection of the figure-8 did not form at vernal equinox or at autumnal equinox. In addition, I recorded four days of sunrise and sunset tracks respectively in spring, summer, autumn and winter, and combined them with sun analemma. The degree of inclination of sunrise or sunset can be used to determine the latitude of the shooting location.
Due to heavy winter and spring rains and frequent summer afternoon thunder-storms, whether it is morning or afternoon, it is not easy to shoot the sun within a fixed period of time in Taipei. Some large gaps in sun analemma indicate that the sun did not show itself to be photographed for up to 20 days, and since sometimes the sun had to be photographed even when it was partially hidden in the clouds, several suns in the picture are not complete! Therefore, in addition to the trajectory of the sun in a year, the Taipei sun analemma can also be used to see the weather patterns in Taipei.
The landscape below sun analemma in the morning is the mountains in the south-east of Taipei. In fact, Taipei is a basin surrounded by mountains. The landscape be-low analemma in the afternoon is the downtown area of Taipei. Note that the tall building in the foreground is Taipei 101 (508 m), which used to be the tallest building in the world from December 1, 2004 to January 7, 2010.

NGC 105 by William Ostling, on Flickr
Full write up here: https://theastroenthusiast.com/ngc-105-from-hubble/

This image from the Hubble Space Telescope displays spiral galaxy NGC 105, which lies 215 million light-years away in the constellation Pisces. NGC 105 appears to be plunging edge-on into a collision with a neighbouring galaxy, but this is just the result of the chance alignment of the two objects in the night sky. NGC 105’s elongated neighbor is actually far more distant and remains relatively unknown to astronomers. These misleading conjunctions occur frequently in astronomy, a great example being NGC 3314: https://theastroenthusiast.com/ngc-3314-from-hubble/

Trapped into Barnard's Loop

Orion - is a constellation that never gets boring and it is probably the most anticipated area of the winter sky. An astrophotographer and a visual stargazer will be tempted to do so... I do not remember how many times I have stayed most of autumn stargazing night longer to watch its sunrise ...

Hello,Today, with as much fatigue as with pride, I present to you my biggest astrophoto project to date, the big Spaghetti Nebula (Simeis 147 or SH2-240) in HOORVB mosaic of 2 tiles.

Full resolution is here : https://astrob.in/043eov/B

It's an object that has always fascinated me, that I dreamed of shooting knowing it wouldn't be easy.
SPOILER: It was worse than that!

It took me 2 months to acquire enough lights to make anything out of it.

Indeed, I shot 14 winter nights between November and January (5 of which played with my nerves with the fog lifting at nightfall without being able to do anything).

You should know that I could not even shoot the Ha during the moonlight because it passed directly over my target and was therefore very close over ten nights per cycle.

Since this project is particularly close to my heart and living in an apartment, I decided to put all the chances on my side by making the necessary route to go shoot where the weather would allow it.

So I shot from the Vosges, I camped in 0 ° C in Alsace, I shot from my astrobro Christope in Moselle, I went south of France to Valensole and I moved on several spots on several nights in this region.A total of 3,600 km of road to acquire the 55 hours of lights retained which consist of:

Tile 1:
Ha -> 71x600 ’’
Oiii -> 78x600 ’’
R G B -> 90x10 '' per filter

Tile 2:Ha -> 94x600 ’’
Oiii -> 78x600 ’’
R G B -> 90x10 '' per filter

While the acquisition was long and complex, so was the processing, I had to work with 400GB of data for a final image of 15 000 x 12 000px.Suffice to say that the PC has smoked!
Once again a big thanks to Christophe who illuminated me with his advices during the processing and gave me invaluable help, thanks also to Nico for his always correct eye!

Saturn and the Polar Hexagon

The polar hexagon of Saturn is unique and truly intriguing phenomenon.

First observed in 19081 by Voyager , it is located at about 78 degree N. The southern pole does not have a hexagon.

The overall diameter is some 18,000 miles (29,000km) and each side of the hexagon is 9,000 miles (14,000km), that is larger than the Earth.

This image was captured from our backyard on a night with excellent seeing. The planet was only about 40 degrees in altitude and the ADC was tuned to counteract the effect of atmospheric dispersion as much as possible.

The C14 was collimated as best a possible and the mono ASI290mm was used with RGB filters with 90sec per filter exposures.

Data was stacked and derotated with Winjupos.

Good evening everyone,

Here is my last post on this Orion and Barnard Loop photo,

I spent the only clear moonless night to try the samyang 135mm f2, because I wanted to have fun doing astrophoto with the lens as well. I absolutely wanted to shoot the constellation of Orion and the Barnard Loop.

It was complicated to image it with a seeing more than hazardous but on 210 shots of 120 seconds I kept only 100 raw.

After some treatment trials, I was happy with my final treatment but it is incomparable with the one done by Philippe Bernhard, you feel very small next to it 😅😅 I've been practicing for a year, I had made good progress in treatment compared to my beginnings but I still have a long way to go 🤣🤣

The Reflexion Nebula - Messier 78

Messier 78 is a blue reflection nebula that is found near of constellation Orion. A reflection nebula is a cloud of dust that reflects light from one or more nearby. The red surrounding colour emission nebula (H-alpha) belong to this constellation (Orion). H-alpha (Hα) is a specific deep-red visible spectral line with a wavelength of 656.28 nm in air.

This is the first serious image taken from my new remot control observatory.
